Note:
• Specifications and the design are subject to possible modification without notice
due to improvements.
*Average current drawn
• The average current drawn is nearly the maximum current drawn by this unit
when an audio signal is input. Use this value when working out total current
drawn by multiple power amplifiers.

CAUTION
• Do not install in:
—Places where it could injure the driver or pas-
sengers if the vehicle stops suddenly.
—Places where it may interfere with the driver,
such as on the floor in front of the driver’s seat.
• Make sure that wires are not caught in the sliding
mechanism of the seats, resulting in a short-circuit.
• Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Protect
all cables and important equipment such as fuel lines,
brake lines and electrical wiring from damage.
• Install tapping screws in such a way that the
screw tip does not touch any wire. This is important
to prevent wires from being cut by vibration of the
car, which can result in fire.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could become
hot to the touch and minor burns could result.
• To ensure proper installation, use the supplied parts
in the manner specified. If any parts other than the
supplied ones are used, they may damage internal
parts of the amplifier, or they may become loose
causing the amplifier to shut down.
• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an improp-
er fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.
CAUTION:
To prevent malfunction and/or injury
• To ensure proper heat dissipation of the amplifier,
be sure of the following during installation.
—Allow adequate space above the amplifier for
proper ventilation.
—Do not cover the amplifier with a floor mat or
carpet.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could become
hot to the touch and minor burns could result.
• Do not install the amplifier on unstable places such
as the spare tire board.
• The best location for installation differs with the car
model and installation location. Secure the amplifier
at a sufficiently rigid location.
• Make temporary connections first and check that the
amplifier and the system operate properly.
• After installing the amplifier, confirm that the spare
tire, jack and tools can be easily removed.
Example of installation on the floor
mat or on the chassis
1. Place the amplifier where it is to be
installed. Insert the supplied tapping
screws (4 × 18 mm) into the screw
holes. Push on the screws with a
screwdriver so they make marks
where the installation holes are to be
located.
2. Drill 2.5 mm (1/8 in.) diameter holes
at the point marked, and install the
amplifier, either on the carpet or
directly to the chassis.
